A CORPO- SHOE-TURNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 763,620, dated June 28, 1904.

Application filed November 12,1903. Serial No. 180,857 (NomodeL) To all whom it may concern;

Be it known that 1, WILLIAM C. MEYER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Shoe-Turning Machines; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to shoe-turning machines for turning the rear or counter portion of a turn-shoe and which comprise a I5 form and a plunger movable into and out of the form and cooperating therewith to turn the rear or counter portion of a shoe over the form.

The present invention is intended primarily as an improvement on the shoe-turning machine disclosed in the application of Andrew Eppler, J r., filed April 16, 1902, Serial No. 103,150.

In the use of shoe-turning machines com- 2 5 prising a form and a plunger cooperating therewith to turn the rear or counter portion of a shoe over the form diflicultyhas been experienced on account of the binding of the upper on the form, the strain put upon the 3 upper by the binding of the upper on the form being often sufficient to cause the seam at the back of the upper to gap or rip and to otherwise injure the shoe and mar its appearance. In the machine of the Eppler application above referred to it has been attempted to prevent the binding of the upper on the form by providing a recess in the rear wall of the form below its rear edge, into which the upper can bend during the turning operation,

4 and by imparting a relative lateral movement to the plunger and form during the turning operation. In practical operation this machine has given satisfactory results; but it has been found that the upper still binds upon the form during the turning operation, especially when the operator is careless in placing the shoe in position on the form or in depressing the plunger or when a form is used which does not accurately fit the shoe. Y

The object of the present invention is to provide means for preventing the binding of the upper on the form as it is turned over the form by the plunger, so that any liability of causing the seam atthc back of the upper to gap or rip or of otherwise injuring the shoe during the turning operation is avoided.

With this object in view the present invention contemplates providing a belt so located as to engage the upper where it tends to bind on the form. During the turning operation the upper is pressed against this belt and the belt travels with the upper as the shoe is forced into the form, so that the binding of the upper on the form is prevented, and the 7 shoe is easily turned without subjecting the 5 upper to injurious strains.

Broadly considered, the invention contemplates the use of any suitable form over which the shoe is turned. It is preferably embodied, however, in a machine provided with a form 7 having a recess in its rear wall, such as is disclosed in the application above referred to, as thereby a space is provided into which the upper can bend during the turning operation,

and the shoe is turned more easily and with 75.

less strain upon the upper. WVhen such a form isused, the belt is arranged to pass over the rear edge of the form and through therecess. Preferably the belt is provided with a tension device, which keeps the belt taut, but still allows it to bend so as to conform to the upper and to the form during the turning operation.

The invention will be readily understood from the accompanying drawings, in which- 8 5 Figure 1 is a View in side elevation of the shoe-turning machine disclosed in the application hereinbefore referred to with theipreferred form of the present invention applied thereto. Fig. 2 is a detail sectional view 9 taken on a vertical plan passing longitudinally through the center of the form; and Fig. 3 is a detail view illustrating in rear elevation the form, the support upon which it is mounted, and the mannerin which the belt which passes over the rear edge of the form is arranged and supported.

Referring to the drawings, 1 indicates the form over which the rear or counter portion of the shoe is mounted. This form is pro vided with a recess 2 in its rear wall beneath its rear upper edge and is secured upon asupport 3, pivotally mounted at 4 to the side plates 5 of the frame of the machine. The recess 2 in the rear wall of the form forms a space into which the upper can bend during the turning operation, so as to relieve the binding action of the upper on the rear wall of the form. The plunger which cooperates with the form 1 in turning the rear or counter portion of a shoe is indicated at 6 and is adjust ably secured in the overhanging end of a lever 7, pivoted at 8 between the side plates 5 of the machine-frame. The support 3, upon which the form 1 is mounted,is provided with a rearwardly-extending horizontal arm 9, which is connected by a link 10 to the lever 7, so that when the lever 7 is oscillated to move the plunger toward the form a lateral movement is imparted to the form toward the plunger. The lever 7 is oscillated from a treadle (not shown) through suitable connections comprising a rod 11, pivotally connected to the front end of the lever. Inthe upper rear edge of the form an antifriction-roller 12 is journaled in position to support the upper at its central rear portion as the upper is turned over the form.

The construction and mode of operation of the parts above described are the sameas those in the machine disclosed in the application above referred to. In accordance with the present invention a belt 13, of canvas or other suitable material, is provided, which passes over the curved rear edge of the form and in close proximity to the outer and inner surfaces of the rear wall of the form. The belt passes through the recess 2 in the rear wall of the form and around a roller 14, the ends of which are engaged by coiled springs 15, secured to arms 16, projecting from the support 3. The roller 14 is thus spring-supported and serves to keep the belt 13 taut, while allowing it to bend during the turning operation. When the shoe is placed upon the form, the rear portion of the upper is engaged by the belt 18, and as the shoe is turned by the movement of the plunger into the form the belt travels with the upper, so that the upper is prevented from binding against the upper rear edge of the form or against the outer or inner surface of the rear wall. The belt yields to allow the upper to be drawn into the recess 2 in the rear wall of the form,and the shoe is turned easily without subjecting it to any strain sufiicient to mar or injure the upper.

While I have illustrated and described my invention as applied to the machine disclosed in the application of Andrew Eppler, J r., Serial No. 103,150, it will be understood that it may be applied to other forms of shoe-turning machines comprising a form and a plunger and may be otherwise embodied without departing from the spirit thereof.

Having thus indicated the nature and scope of my invention and having specifically described a construction embodying-the same in its preferred form, I claim as new and desire to secure by Letters Patent 1. A machine for turning the rear or counter portion of a turn-shoe, having, in combination, a form over which the shoe is turned, a plunger movable into and out of the form, and a belt located to engage the upper where it tends to bind on the form and arranged to travel with the upper as the shoe is turned, substantially as described.

2. A machine for turning the rear or counter portion of a turn-shoe, having, in combination, a form over which the shoe is turned provided with a recess in its rear wall, a plunger movable into and out of the form, and a belt passing through the recess and over the rear edge of the form, substantially as described.

In testimony whereof Iaflix my signature in presence of two witnesses.
